5 claims. (o1. 6237.s)

f My invention relates Ato refrigerators and has for its object to provide a new and eficient refrigerator of the type in which ice is used.

A further object is to provide a refrigerator which is so constructed that a forced circulation is created therein, said circulation to draw air over broken ice and then force it along the refrigerating chamber and return it back over the ice again in a continuous flow of air.

A further object is to provide a refrigerator Which will require less ice, will be more efc'ient, and will keep more area of refrigerating space cool with less power and less ice than possible with other types of refrigerators.

A still further object is yto provide a refrigerator which will bev easilyY iced, which when iced may be closed without the usual trouble in icing the refrigerator, and winch will not require the ice drawers commonly used in open face store type of refrigerators. y

A still further object is to provide an ice box for small stores in which meats may be kept for a longer period of time than is possible in automatic electric refrigerators and at the same time the ice used in the present invention keeps the meat moist instead of drying it out. I

These objects I accomplish with the device illustrated in the accompanying drawing in which similar numerals and letters of reference indi--Y cate like parts throughout the several-l views and as described in the specification forming a part of this invention and pointed out inthe appended claims.

in the drawing in which I have shown my invention:

- Figure l is a longitudinal section of a refrigerator with arrows to show the travel of the air currents.

Figure 2 is a section through the refrigerator showing the air fan, driving motor, collecting air chamber, and icer compartment.

Figure 3 is a View of a modified form of making one end of the refrigerator, showing the air concentrated into an enclosed channel in the end of the compartment.

Figure A is a vertical section of the end of the refrigerator shown in Figure 3.

In the drawing I have shown the refrigerator casing as A, which casing is divided into three compartments, namely, the ice chamber B, the display refrigerator chamber C, and the chamber D, in which articles may be kept cold, but are not in sight and which is commonly called the blind chamber. Y

Along the bottom of a portion of the ice chamber B, Iform a channel I` leading into a distributing or collecting compartment 2 which also has openings 3 therein through air' is drawn from the ice chamber". Ports I a lead into the chanel I from the chamber B through the 5 top side' thereof to insure complete cooling of the air. This air is then drawn into a fan chamber F through the duct 4 and is forced up through a distributing duct 5( into a horizontal distributing pipe 6. The pipe 6 is formed along the entire 10 length of the top of the casing A iii the chamber C and pipe 6 is' provided with ports 'l therethrough, through which the cold airis forced into the chamber C. These ports 'I are controlled by Va. perforated plate 8 carried in the p-ipe 9 and 15 controlled ty handles' s depending through slots EI in the bottoni plate IU of the' pipe t. The perforation's of the plate I'iay he brought into or out of alignment with the p''rts l' -to control the ai'frci the pipe G into the show casecham- 20 bei' C. The slots` I I thr'ngh which the handles Ve'ite'dY are fad hth Ig and Wide to' allowv the plate to be r'ved' either sideways or longitudinally'.

The chamber C is divided from the' chambers B 25 and n by tie renovable plates' rt. As shown in Figure I the air currents' zzafter passing from the ports 1 and through the lcooling chamber C, pass down thugh a slot I5 at the end of the trays I5 intouthepupper portion of the blind 30 storage' chamhe'r D. This' air then passes through this chamber and o r" the top' of the partition A IT through an' opening I8 thcre'above' into the' ice chamber C. The opening I8 is made adjustable as to size by the adjustable plate I8a which is 35 mounted onto the top of the partition I'I. The icing method provided for this refrigerator consists of a counter box I9 formed on the back side of the casing A with the top 29 of the box hinged to the casing A. The back 2I is hinged 40 to the back 22 of the box I9 and the sloping bottom 23 is solid as shown. The inclined opening 24 into the ice chamber B is formed through the back wall of the casing A and is provided with an inclined closure block 25 which block is pro- 45 vided with handles 2S and which block is taken out of the opening and the ice is then dumped into the box I9 and down the inclined opening 25.- into the icc chamber. The ice is all placed in the refrigerator through this opening and what 50 ice is in the box I9 is also swept into the ice chamber and the closure block 25 is again inserted into the opening. This `closure block is insulated like the casing A. The face 2| is then closed up and the top moved down on its hinges to lock into 55 the face 2| holding the box I9 closed until more ice is necessary. The top 20 has a ledge 21 formed therealong to engage the outside of the face 2| to hold the face in place.

As shown in Figures 3 and 4 a return controlled conduit may be provided for the end of .the casing with a conduit 29 secured to the end of the casing through the closed end of the plate I5. This conduit has the top end 30 Wider at the top and tapered into a channel and has the bottom end 3| controlled by an adjustable channel B2. The channel may be either moved up or down as desired to change the discharge from the conduit I9 into the chamber D. A slot is provided in the channel 32 to provide for adjusting it and thumb screws 33 are provided for quick adjustment thereof.

A clean out plate 35 is provided at the bottom of the partition l1 to allow for washing out the entire bottom of the casing.

The motor M for the fan F is mounted outside the casing on a suitable bracket and a shaft Ml is extended in through the side of the casing to drive the fan F.

Having thus described my invention I desire to secure by Letters Patent and claim:

1. In a refrigerator of the class described, the combination of an ice compartment; a cooling compartment adjacent thereto; a sho-w case compartment over the entire surface of the cooling compartments; an opening in the back side of the ice compartment formed on an angle to ll the ice compartment; an insulated closure block for said opening; a counter box formed on the back side of the refrigerator having the lid hingedly connected to the refrigerator casing to allow the lid to be raised to ll the ice compartment therethrough; and a sloping bottom to the counter box to distribute the ice into the opening; and means to draw ice cooled air from the ice compartment and force it into the show case refrigerating compartment, and back through the cooling compartment into the ice compartment.

2. In a refrigerator, the combination of a casing divided into an ice compartment; a cooling compartment on the same level as the ice compartment; and a refrigerating display compartment over the other two compartments; a conduit in the bottom of the ice compartment, a fan mounted in the ice compartment to draw air through said conduit around the ice; a distributing pipe leading vertically from said fan and horizontally along the top of the display compartment having ports along the horizontal portion which extends through the refrigerating compartment; means to control the opening of 5 said ports; a'return conduit at the end of the casing leading from the refrigerating display compartment into the cooling compartment; and

a partition having an adjustable plate along the top side thereof to divide the cooling compartl ment from the ice compartment and. force the air over the top of the partition down into the ice for a continued cycle.

3. In a refrigerator of the display type, the combination of a long display refrigerating coml partment; a blind cooling compartment and an ice compartment both disposed under the display refrigerating compartment; a ported conduit along the bottom of the ice compartment; a fan chamber carrying a fan in said ice compartment to collect the cool air through said ported l conduit and distribute the cool air into the display compartment through adjustable ports; an opening from one end of the display compartment down into the cooling compartment; and an opening through the partition between the l cooling compartment and the ice compartment to draw the air from the display compartment through the cooling compartment into the ice compartment.
